Another place to check is FanFiction.net. There are a ton of Star Wars - related fanfics on this site as well. Just use the search function and type in 'baby Leia' to see what pops up. However, the quality may vary, so you might need to do some sifting.
One popular baby Leia fanfic could be the one that focuses on her early days on Alderaan, imagining her life as a princess in training. It might describe her interactions with the court and how she starts to show her strong will even as a baby.
One interesting 'baby Luke and Leia fanfiction' could be the one where they are hidden away on a peaceful planet as babies. It shows their early days in a more detailed and imaginative way.
One idea could be a story where Padme's spirit somehow guides Leia throughout her life in the Rebellion. Leia could have visions of her mother's wisdom, which helps her make crucial decisions.
Well, a really interesting plot could be that Anakin, instead of turning completely to the Dark Side, is influenced by his encounter with Baby Leia. Maybe he starts to have doubts about Palpatine's plans when he holds her. And then he tries to find a way to balance the Light and Dark within him while ensuring Baby Leia's safety. It could also be that there's a hidden prophecy about Baby Leia that Anakin stumbles upon, and he has to decide whether to follow it or not, which would put him at odds with the Sith and the Jedi alike.
One popular 'leia fanfic' might be those that explore her adventures before the events of the main Star Wars movies. For example, stories could focus on her diplomatic training on Alderaan.
The setting also plays a big role. The seedy, dangerous environment of Jabba's lair adds a sense of foreboding and adventure to the story. It's a place full of strange creatures and shady characters that Leia has to navigate.
In many Star Wars fanfics, the relationship between Leia, Anakin, and the concept of a 'ghost' can be really interesting. Leia is Anakin's daughter, and in some fanfics, Anakin's ghost might play a role in guiding or protecting her. For example, he could appear to her at a crucial moment, sharing some wisdom from the Force that helps her make a difficult decision. This could add a new layer of depth to their family connection that wasn't fully explored in the movies.
Rather than discussing such improper fanfics, we could explore fan - made content that adheres to the values of the Star Wars universe, such as fan - made short stories about the Jedi's training or the Rebellion's battles.
